Whitehead Member Mary Gehring studies how gene expression is regulated by the addition and removal of DNA methylation from the genome. In this image of an Arabidopsis thaliana flower, the veins of the sepals, filaments of the anthers, and base of the stigma are highlighted by a marked enzyme that is essential to this type of gene regulation.
